Specification of Letters Patent.

Patented June 15, 1915.

Application filed November 11, 1912. Serial No. 730,632.

To all whom it may concern:

Be it known that I, FRANK JAGER', a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented new and useful Improvem'ents in Car-Doors, and of which the following is a specification, reference being made to the accompanyingdrawings.

My invention relates generally to doors, and has reference more particularly to that typeof railway car door provided with a port and an outwardly swinging closure therefor, and which door is slidable longitudinally of the car to close the door openmg.

One of the main objects of this invention is the provision of a movable meansmounted at the side of the door opening adapted for movement to an operative position when the opening is closed whereby the door is held against sliding and the closure against outward swinging movement. Another object is the provision of such movable means designed to render a door of this character proof against leakage, and which may further present a series of broken joints against the entrance of water through interstices at points of vertical contact between car and door members.

A further object is the provision of novel cooperating members at the juncture of door and threshold designed to facilitate the unloading operation particularly when grain scoops are used to unload grain. A still further object is to provide improvements in this type of ported sliding door so as to effectually cooperate with the movable means to which reference has already been made.

These together with such other objects as may hereinafter appear or are incident to my invention, 1 attain by means of a construction illustrated in preferred form in the accompanying drawings, wherein:

Figure 1 is an elevation of the inside face of my improved door which is shown applied to a box car, the car body being broken away in order to accommodate the figure.

Figure 2 is a longitudinal sectional view of Figure 1.

Figure 3 is an elevation of the outside face of the door. Figure 4: is a vertical section on the line IV-IV, and Figure 5 is a longitudinal sec tion 3on the line VV respectively of Figure Figure 6 is a similar view of Figure 5, except that the door proper is shown at open position.

Figure 7-is a view in perspective ofone of the pivoted angular jamb members in position against the door and door post and presenting a series of broken joints to prevent the entrance of water therebetween.

F igures 8 and 9 are detail views slightly enlarged to better illustrate certain features of my invention. 7

My improved door is particularly adapted for use with cars engaged in grain carrying service, and entirely eliminates the me cessity for employing temporary grain doors commonly used in such connection. To this end I provide an inside door provided with one or more ports suitably arranged therein for loading and unloading grain and other commodities, without having to slide the door proper longitudinally the car for the purpose of obtaining access to the car interlor.

I preferably arrange one of the ports in a location sufiiciently high enough for the reception of grain spouts, and of such width to fully provide for their effective manipulation to properly load the car. Another port is conveniently arranged at the lower end of the door for the quick unloading of grain by the usual scoops, or for the expeditious handling of ordinary way freight. A centrally located port may also be arranged in the door proper if desired for the unloading of such a commodity as coal, with a minimum expenditure of labor.

The ports extend substantially the width of the-door opening, and are provided with outwardly swinging closures or doors having tight joints with surrounding door members. Each of the closures may-be provided with any desired fastening means, which latter are relieved against excessive pressure from a load within the car by movable jamb members which are pivoted to suitable supports at the sides of the door opening. Each of the members has movement inwardly on a vertical axis from a position substantially out of the door and closure or closures to retain the former from sliding and the latter from outwardly swinging movement opening to a substantially right angular formed to cover and rest in the angles formed by the contiguous outer faces of its support and door and continue laterally to the'adjoining vertical edges of door and closures, and in this way desirably provide what might'be termed a. series of broken joints at these points extending vertically from the track beam to the threshold of the car and laterally from the support to the closures, in order to effectually prevent the entrance or percolation of any water or foreign substances between the car s1d1ng and the doorfor between the door proper and the closures which cover the ports.

These pivoted jambs as already referred above, furthermore constitute an additional means of support for the closures, particularly at their side portions.

In order to prevent grain scoops from catching on the ordinary type of lower guide track, I provide a track having an inner inclined surface so as not to obstruct or hinder the effective operation of such scoops, or whatever other means is adopted for unloading freight. This track also has its outer surface suitably perforated to register with apertures provided in the threshold of the car, so that in the event of any water collecting under the lower edge of the door it may be at once drained away.

In carrying out my invention as applied to a box car I provide an inside door 10 to close the door opening and comprising the horizontal rails 11 and upright frame members 12, the said door being suitably supported in the car by means of hangers 13 having sliding engagement with a track 14 bolted to the car lining or track beam 15 above the opening. The upright members- 12 havetheir lower ends in sliding engagement with a lower rail 16 extending across the threshold 17, so that when pressure is applied to the door it is guided by the two tracks either to closed position against a cleat 19 when the members 12 are brought to rest up against the inside faces of the door posts 18; or conversely to open position to move clear of the door opening and behind a partition 33 which extendsup-v wardly from the floor of the car to a point Y above the grain line of the car.

The conformation of the lower track 16 is clearly shown in Figure 9,-sa1d track extending cross the threshold from one door post to apoint within the partition 33 The track proper consists in an outer-flat bearing surface 16", a longitudinal shoulder 16", an inner surface 16 inclining upwardly from the "floor to the. shoulder but spaced away therefrom by a depression 16 adapted toreceive for sliding movement therein a downwardly depending flange or shoe 24 bolted to the lower portion of the door members 12. It will readily be seen that this lower track affords positive guiding movement to the door, so that when moved to closed position the members 12 are close up to and against the door posts, and at the same time it offers no abrupt angle to unloading means. The lapped edges of the lower closure and uprights 12 rest upon the surface 16 and against the shouder 16 and in the event of any water collecting at this point, it is at once drained away by holes 25 provided in the flat surface 16 and then through apertures, 26, cut through the threshold 17 to correspond therewith.

To form the ports or openings already referred to, I preferably employ three of the horizontal rails 11, suitably spaced away from each other and having their ends fastened to the-two uprights 12, which latter being of greater relative thickness than the rails with the exception of that portion of the upper rail resting against the track beam 15 above the door opening, project slightly outward beyond the vertical plane 8f the outer surface of the other door mem ers.

Hingedly connected to the horizontal rails in the same vertical plane and adapted to have swinging movement to open and close the openings between the said rails and uprights are closure-s20, 21, and 22 preferably provided centrally at their lower ends with any fastening means 23. The edges of the closure members are lapped to firmly seat when in closed position oncorrespondingly recessed or lapped adjacent edges ,of the door rails and uprights to form tight oints, as 10, exceptthe lapped lower edge 20 of the closure 20 which rests against and seats on the lower rail 16.

Referring now more particularly to Figure 3, it will be noted that the ports and their closures have slightly less width than the door opening to permit the easy manipulation of the said closures and it is apparent that when the door is closed the uprights 12 which rest againstthe door posts 18 each preferably present an angular abutting surface indicated at 12, inasmuch as the uprights arerelatively thicker and do not lie in the same'vertical plane as the other door members and closures. These abutments hold the door proper slightly away from the door posts and car lining members so that when the door is moved the latter will offer no obstruction to any fastening means thereon.

Pivotally mounted in the doorway to each of the door postsand vertically in a line preferably intermediate each of their inner and outer faces, is a movable weather jamb 28 of angular shape extending from the track beam to the threshold of the car, having a plurality of flanged surfaces as shown in the preferred manner in Figure 8, thus providing a series of angular surfaces to fit in and protect whatevei angles are formed by the various members in contiguity at the sides of the door opening.

The outer flange 29 and inner flange 30 of the jamb 28 are oppositely disposed to each other, and intermediate these said flanges and forming the preferred connection therebetween is an angle iron portion 31, the inner flange 30 being pivoted to a web 32 secured to the door post 18. Formed on the free edge each of the flanges 29 is a lug 37 slotted to receive a staple 38 on the door proper, the lug being clamped thereto by the usual seal pin 39.

When the door is closed, and the jamb. given inward movement to a lateral position with respect to the door, the inner flange 30 rests against the door post, theouter flange 29 bears against the adjacent vertical edges of the closures and door and incidently against other portions of the door members in vertical alinement therewith, and the connecting portion 31 together with the flanges form a continuous cover or seal to joints or at points of contact between the various members forming the angle at the side of the door opening, and particularly between the door and door post.

The outer edge of the lug 37 is slightly bent outwardly to provide a hand-hold for the easier operation of the jamb member, and should it bind in its outward movement by reason of pressure from within the car, a tool may be inserted at this point in order to obtain the desired leverage. To permit full outward movement of the jamb to a position entirely clear of the door openiing, I recess the outer face of the door port at 1-8 to receive the inner portion 31 of the jamb, and it is also suitably cut away to accommodate the bend edge of the lug. The employment of such metallic angular member at both sides of the doorway and in this the weakest part of freight car construction is particularly advantageous. The lower extremity of the j amb may be flanged outwardly if desired, said flanged portion being adapted to rest upon the threshold to shed water.

It will readily be seen that irrespective of the fastening means 23 the closures are held down in closed position tight on their respective seats, the said fastening means being necessary only where the car isloaded with grain or like commodities possessing some degree of fluidity, checking any involuntary opening of the closures at a time coincident with the outward movement of the jambs, as will be understood.

The door opening has easy movement along the tracks and when it becomes necessary to slide the door'proper for the loadin'g or unloading of bulky freight, any possibl e obstruction by shifted freight to this opening movement is obviated by the partition 33 which is spaced away by the supporting uprights 3 and 35 from the car lining to accommodate the entire door when open.

When the door proper is closed and grain is being loaded into the car through the upper port in the door, no leakage of grain through any interstices formed by warping of door posts, or other members, can possibly occur before closing of the movable j ambs, inasmuch as the rear end of the door is entirely-inclosed by the partition and its supporting uprights 34 and 35,-and furthermore the cleat 19 adequately protects the front end of the door. Access to the partition is permitted through an opening at its lower end, normally closed by a swinging door 36.

From the foregoing, it is plainly evident that in my improved construction, allhorizontal joints or points of contact between door members and closures are lapped, providing what might be termed a watershed in this respect, and all vertical joints are not only lapped but they are in addition covered and protected against the entrance of water. This door is positively tight against severest weather conditions, is durable in construction and has no involved parts to get out of order.

Having thus described my invention and illustrated its use what I claim as new and desire to obtain by Letters Patent is the folowin 1. n a railway car having a doorway frame and a doorway opening, the combination of a sliding door for said opening having a port, an outwardly opening closure member for said port hingedly mounted on said door and of a lesser width than the doorway opening, and an inwardly swinging holding member for holding said closure member in closed position, said holding member being pivotally supported on the frame at a point appreciably removed from the face of the closure member and adapted when swung inwardly to lie between the closure member and the point of pivotal support and laterally thereof to engage the door and closure member whereby to hold the former against sliding and the latter from swinging outwardly when subjected to pressure.
